More magic QR codes

It seems that permits for lorries in to Kent are a QR code as well, and it seems they are really good at validating number plates?!

This decodes as:-

This is base32, which is somewhat nicer for QR code encoding as it fits entirely in the alphanumeric coding (which is digits, upper case, and a few symbols).

It decodes as two parts: some JSON and a binary block.

{"v1":["a7d1aab1-6357-4a86-919b-9c723e1602e0","BORISMOLESTSFISH","3754800","86340","1641616","K","G","K","-"]}

So, once again, a digital signature, but made to be a smaller code than the NHS codes.
